Modelling Compressible Multiphase Flows
We give in this paper a short review of some recent achievements within the framework of multiphase flow modeling. We focus first on a class of compressible two-phase flow models, detailing closure laws and their main properties. Next we briefly summarize some attempts to model two-phase flows in a porous region, and also a class of compressible three-phase flow models. Some of the main difficu...
متن کاملMulticore/Multi-GPU Accelerated Simulations of Multiphase Compressible Flows Using Wavelet Adapted Grids
We present a computational method of coupling average interpolating wavelets with high-order finite volume schemes and its implementation on heterogeneous computer architectures for the simulation of multiphase compressible flows. The method is implemented to take advantage of the parallel computing capabilities of emerging heterogeneous multicore/multi-GPU architectures. A highly efficient par...
متن کاملAdaptive Characteristics-Based Matching (aCBM): a Method for Interfacial Dynamics in Compressible Multiphase Flows
This work is motivated by the need for a high-fidelity numerical treatment of compressible flows with multimaterial interfaces. Of particular interest are immiscible flows with high Acoustic Impedance Mismatch (AIM) interfaces, such as those between gases and liquids, under both weak and strong shock wave conditions. These types of flow are encountered in numerous generically-important processe...
متن کاملBiorthogonal wavelet-based full-approximation schemes for the numerical solution of elasto-hydrodynamic lubrication problems
Biorthogonal wavelet-based full-approximation schemes are introduced in this paper for the numerical solution of elasto-hydrodynamic lubrication line and point contact problems. The proposed methods give higher accuracy in terms of better convergence with low computational time, which have been demonstrated through the illustrative problems.
متن کاملA GPU-based Multi-level Algorithm for Boundary Value Problems
A novel and scalable geometric multi-level algorithm is presented for the numerical solution of elliptic partial differential equations, specially designed to run with high occupancy of streaming processors inside Graphics Processing Units (GPUs). The algorithm consists of iterative, superposed operations on a single grid, and it is composed of two simple full-grid routines: a restriction and a...
